Oneof the things that I try to emphasize in the reports -- because wehaven't yet even had to face a report to Congress -- is, we're going todo it lots of ways but I think -- to make sure that we've covered allour bases, we're going to try estimating it one way, we'll look at thedirect numbers, we'll try some different multipliers, we'll be lookingat other studies, we'll be doing some microeconomic analysis to see if,you know, a county had a whole lot of government spending; does it showup in the county employment data?

这份报告中，我要强调一件事情――由于我们甚至还不用讨论一份提供给国会的报告――但是，我认为，我们有多种方法可以做到，――这件事情就是，要确定我们涵盖了所有的基本情况，我们会用一种办法尽量去估计它，我们将关注直接的数据，我们也会试试其他的乘数，我们也会看看其他的研究，我们会做一些微观经济分析，你知道，看某些县是否有很多的政府支出；这个县的就业数据对此是否有所揭示。
